    Another "observation"... Each of the charging instances described below were with the iPhone below 20%, and then charging to 100%. Also, iPhone use was essentially the same.

    1. For 2 consecutive days, I charged the iPhone at work through a power surge protector/suppressor. The iPhone charge lasted about 24 hours. I thought this was rather strange, since I've gotten closer to 36-48 hours before, but not paying attention to where or how I charged the iPhone. But I think that most of my charging was at home, and rarely at work.

    2. 3rd day, I charged using the USB port on my computer. The iPhone lasted almost 48 hours.

    3. Next 2 days, I charged at home, straight into the wall socket. Each time, the iPhone lasted almost 48 hours.

    4. Finally, back at work, I charged directly through the wall socket. Again, the iPhone lasted almost 48 hours.

    It appears that charging through a power surge protector/suppressor has some kind of effect on how the battery charges... and therefore how long the charge holds?

    Any thoughts?

    I'm generally not a heavy user... especially during the work week... maybe 5 hours a day?

    But, for my general use, it was interesting to me that with essentially consistent daily usage, how long the battery lasts appears to coincide with charging through a power surge protector/suppressor or not.
